Casamigos Halloween Party 2018

This weekend saw Casamigos founders George Clooney, Rande Gerber and Mike Meldman throw not one but two Halloween parties at Las Vegas's Aria Resort and Casino, where the tequila cocktails were flowing both nights. The great and the good from Hollywood were in attendance, with Harry Styles making a memorable appearance dressed as Elton John, Cindy Crawford dressed as an air stewardess and her husband Rande and co-host George Clooney donning pilot uniforms. Kendall Jenner - dressed as an Austin Powers fembot - played a surprise DJ set, and guests crammed into the slow-motion photo booth in between mouthfuls of mini lobster mac and cheese, truffle fries and chicken tacos. On a side note, we were disappointed to see that newlyweds Princess Eugenie and Jack Brooksbank weren't in attendance (Brooksbank works for the tequila brand), but we can only assume that they're currently honeymooning.
